7.2 Types of Awuatic and Terrestrial Pollution Flashcards
Persistent organic pollutants (POP)
carbon based and synthetic compounds that are super resistant to decomposition or degradation and are toxic to organisms and is easily transportable to other places
how many categories are POPs sorted into and what are they
3:
pesticides
industrial chemicals
byproducts
global distillation aka
grasshopper effect
grasshopper effect
the process by which POPs evaporate in warmer climates and then move to cooler areas and condense into solid forms at the base of food webs so they’re absorbed like nutrients into primary producers and then on
what organisms have the most POPs and why
the ones at the top of the food webs bc of biomagnification
how are humans mainly exposed to POPs
contaminated things u ingest and contact and inhalation
how do POPs effect humans
they’re carcinogens and can cause other human disorders
where do humans get most POPs from
from the air or from fish or foods high in fat
Stockholm convention on persistent organic pollutants
international treaty that was made to protect human health + the environment against POPs that basically requires ppl to use or eliminate POPs from human activities and with awareness and education
biggest nutrient culprit of eutrophication
phosphorous
how do bacteria contribute to eutrophication
dead algea turn into bacteria food and they use O2 so deplete it more
main cause of eutrophication bad effects
algea uses up all oxygen for other organisms so less diverse
dissolved oxygen concentration and biological oxygen demand directly or inversely proportional
inversely
